CEGL005775 Viguiera parishii - Eriogonum fasciculatum Desert Shrubland
Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: Parish''s Goldeneye - Eastern Mojave Buckwheat Desert Shrubland
Colloquial Name: No Data Available
Hierarchy Level: Association
Type Concept: This shrubland association is often found on rocky, granitic and volcanic uplands at mid to upper elevations across the Mojave Desert in Arizona, California and Nevada. It is characterized by an open to moderately dense shrub canopy (4-41% cover) codominated by Viguiera parishii and Eriogonum fasciculatum. Many other shrubs may also be present. Occasional emergent Juniperus californica and Pinus monophylla trees are sometimes present. Herbaceous cover is highly variable, ranging from 2-90% cover, and composed primarily of forbs. Stands occur primarily on dry, rocky hillslopes to steep ridges that experience colluvial disturbance and/or erosion from intermittent flooding in drainages and washes. Sites include a variety of upland surfaces from toeslopes to midslopes extending onto the upper alluvial fans from approximately 700-1450 m elevation. Sites are gentle to steep slopes on all aspects. Soils usually range in composition from clay loam to loamy sand, and occasionally sand. They are derived mostly from alkali-granite (alaskite) substrates, but occasionally other igneous types such as rhyolite and basalt or gneiss.

Floristics: The vegetation is characterized by an open to moderately dense shrub canopy (4-41% cover) codominated by Viguiera parishii and Eriogonum fasciculatum with Acacia greggii and Cylindropuntia acanthocarpa present (Evens and San 2006, Evens et al. 2014). Many other shrubs may be present, including Ambrosia dumosa, Ephedra nevadensis, Ferocactus cylindraceus, Krameria erecta, Larrea tridentata, Stephanomeria pauciflora, and Yucca schidigera (Keeler-Wolf et al. 1998a, Evens and San 2006, Evens et al. 2014). Occasional emergent Juniperus californica and Pinus monophylla trees are sometimes present. Herbaceous cover is highly variable. If present, the herbaceous layer ranges from 2-90% cover and is composed of native forbs Amsinckia spp., Camissonia spp., Chaenactis spp., Cryptantha spp., Mirabilis laevis, Salvia columbariae, and Sphaeralcea ambigua and exotic annuals Bromus madritensis, Erodium cicutarium, and Schismus barbatus (Keeler-Wolf et al. 1998a, Evens and San 2006, Evens et al. 2014).

Sites are gentle to steep slopes (0 to 31°) on all aspects. Soils usually range in composition from clay loam to loamy sand, and occasionally sand. They are derived mostly from alkali-granite (alaskite) substrates, but occasionally other igneous types such as rhyolite and basalt or gneiss (Keeler-Wolf et al. 1998a, Evens and San 2006, Evens et al. 2014).
Geographic Range: This shrubland association is often found on rocky, granitic uplands across the Mojave Desert in Arizona, California and Nevada and was sampled in Lake Mead National Recreation Area and Mojave National Preserve. It also extends into the Little San Bernardino Mountains in Joshua Tree National Park.
